Anyone else have a photo-based identification course having this problem?

When I created my tropical reef fish identification course, if an entry in my course database had multiple photos, memrise would only pick one photo for you to look at when reviewing. I designed my course around that. But now, I see that memrise lets you scroll through all of the photos when you’re being quizzed, so if you don’t know the right answer from one photo, you can just look at the others. I can see how that could be very useful for some courses, but it completely ruins mine. I posted a request about it here, take a look:

Repair the community courses, 3: Show one photo, not all

Has anyone else made a course like this and run into this problem? Do you know of a workaround or way to fix it for your course, that I could use on mine?
